Answer 1

The energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.

Energy supplied by the lamp

The energy supplied by the lamp is calculated as follows;

E = Pt

E = IVt

where;

• I is current = 0.4 A
• V is voltage = 12 V
• t is time = 5 mins = 5 x 60 s = 300 s

E = 0.4 x 12 x 300

E = 1,440 J

Thus, the energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.
